Apache Bahir IoT Demo

This demo provides a Web Application that simulates devices collecting metrics from a elevetor and submits these metrics to a MQTT server using a diffeferent topic for each metric.

It also provides a Spark Application that subscribe to the MQTT topic using the Apache Bahir MQTT streaming connector.

Setting up the infrastructure

Boostraping the MQTT server

We boostrap a MQTT Mosquitto server using publicly available docker image

docker run -ti --name mosquitto -p 1883:1883 -p 127.0.0.1:9001:9001 toke/mosquitto:latest

If you get an error because you already have an existent exited container with the same name, issue the command below

docker rm -f mosquitto

Bostrap the web simulator

cd web-simulator/simulator
node app.js

Note: When starting for the first time, you need to use npm to install required dependencies

cd web-simulator/simulator
npm install
node app.js

Then access the simulator in your browser

 http://localhost:6001

Starting your Spark Application

Now we are ready to submit our Spark Application that will subscribe to some MQTT topics and start processing data

cd spark-iot-analytics
bin/runStreaming.sh

The command above will build the application and submit it with it's required dependencies

You can’t perform that action at this time.
